4. In VLIW the decision for the order of execution of the instructions depends on the program itself.
a) True
b) False
View Answer

Answer: a
Explanation: In other words, the order of execution of instructions has nothing to do with the physical hardware implementation of the system.

5. The parallel execution of operations in VLIW is done according to the schedule determined by __________
a) Task scheduler
b) Interpreter
c) Compiler
d) Encoder
View Answer

Answer: c
Explanation: The compiler first checks the code for interdependencies and then determines the schedule for its execution.

6. The VLIW processors are much simpler as they do not require of _________
a) Computational register
b) Complex logic circuits
c) SSD slots
d) Scheduling hardware
View Answer

Answer: d
Explanation: As the compiler only decides the schedule of execution the schedule is not required here.

8. The following instruction is allowed in VLIW:

f12 = f0 * f4, f8 = f8 + f12, f0 = dm(i0, m3), f4 = pm(i8, m9);

a) True
b) False
View Answer

Answer: a
Explanation: The above mentioned instruction is a complex 48 bit instruction used to perform operations on floating numbers.
